>What has changed is the inclusion of spyware technology on the device that can be weaponised to basically report on anything.
- You are running a closed source proprietary OS that you cannot verify is not already doing anything.
- This could theoretically already be weaponized (with the existing server-side implementation) by getting someone to download a file to a folder that iCloud automatically syncs from.
>iCloud is opt-out.
Yes, and that's how you opt out of this scanning. It's the same opt-out as before.
>Under the guise of something no-one can genuinely be against (think of the children!) they have now included a pretty generic snitch into your phone and made everyone accept it.
I dunno what to tell you. I think the system as designed is actually pretty smart[1] and more transparent than before.
If you used iCloud before, and you're putting photos up that'd be caught in a hash comparison, you've already got a snitch. Same with any other cloud storage, short of hosting your own.
[1] I reserve the right for actual bona-fide cryptographers to dissect it and set the record straight, mind you.
